STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent NO. 585,600, dated June 29, 1897.

Application filed January 15, 1897. Serial No. 619.294. (No model.)

To It whom it may concern:

Be it known that I, GIOVANNI B. SICOARDI, a citizen of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Street-Sweeping Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to street-sweepers; and it is the object thereof to provide a handsweeper which will possessall the advantages of a horse-machine and that will be of such simple construction that the cost of the same and the liability of its getting out of order will be reduced to the minimum.

The invention relates also to the details of construction which are particularly adapted to-the machine of this particular description.

The device includes in a hand-machine a suitable skeleton frame supported upon front and rear wheels and a brush and an endless chain of buckets driven from the supportingwheels.

It also includes the details of construction as hereinafter described, and particularly pointed out in the claims.

The invention is illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation of the device. Fig. 2 is a plan view of the same. Fig. 3 is a detail view of the edge of the bracket secured to one of the diagonal braces and component parts. Fig. t is a sectional view of the same on the line 3 3. Fig. 5 is a detail view of the central casting connection between the two parts of one of the diagonal braces. Figs. 6, 7, and 8 are detail views of the scraper, and Fig. 9 is a detail front elevation of one end of the machine.

The two rear supporting-wheels 1 1 of the machineare journaled on an axle 1, extending between the same, over which is fitted the sleeve 2, having each of its ends secured in the cups 4, projecting from the centers of the casting 5, said casting having sockets to receive the adjacent ends of the upper and lower diagonally-extending braces 6.

The upper ends of the upper braces are connected by a rod over which are fitted the wooden sleeves 7, which form the handles or gripping-surfaces for the operator of the machine. Arms 8, loosely journaled at their upper ends on the axle 1 outside of, but adjacent to, the castings 5, extend downward substantially at right angles to the braces 6 and have their lower ends fitted to receive the j ournals of the brush-roll 9, said journals extending entirely through said arm and carrying gears 10, which mesh with larger gears 11, fixed directly to the spokes of the driving-wheels 1, and thus the brush-roll is rotated as the machine is moved. The brush-roll will normally be held against the surface to be swept by its own weight, as the arms 8 are loosely journaled but to provide means for holding it in a determined position, so that the pressure upon the surface will be uniform, I pivot to each of the arms 8 in proximity to the brush-roll the lower end of an adjustable arm 12, said arm being slotted near its upper end to permit of the passage of the shank of the butterfly-nut 12 into a threaded opening in the upper brace 6. 4

To raise the brush to clear the surface so that the machine may progress without the 'roll sweeping, a bail 13 is pivoted to the arms 8 near the journals of thesaid roll, and a chain 1% is connected at each of its ends to the intermediate portion of this bail. The chain 14; passes over a roller 15, connected by a short chain 16 to a winding-drum 17, journaled in the bifurcated end'of an arm 18, ex-

tendin g laterally from the handle. This drum carries a suitable crank and handle for winding the same to lift the brush-roll and a suitable ratchet-wheel 20, with which engages a pawl 21, freely pivoted to the side of said arm 18 to prevent the rearward rotation of said drum. To raise the brush-roll, the nuts 12 are loosened and the drum wound up, which will wind up the chain 16 and lift said brush through the chain 14 and the bail. The pawl will now hold the drum against rearward rotation and the brush-roll in raised position until it is manually thrown out of engagement with the ratchet-wheel, when the brushwill fall.

The lower ends of the lower braces 6 are securely bolted to the rear ends of the side frames 22, to which the platform 23 is bolted. Near the rear ends of each of these frames an opening 24 is cut, and to the outer faces of the frames the plates 25 are bolted, these plates crossing the opening and having shallow recesses in their upper edges coinciding with said opening. A flat curved bar 26, extending beneath the platform, has its ends projected through said opening and freely supported on said plates 25 within their recessed portions. To this bar a series of scrapers are bolted, these scrapers being of inverted- U shape with beveled ends. As the machine progresses these ends come into contact with the hardened manure and the like on the street-surface and serve to loosen the same, so that it may be removed by the brush.

Centrally from each side of the platform a vertical standard 27 extends, on the upper ends of which a half of a clip 28 is seated, the other half of the clip having an extended fiat portion which is bolted to the upper end of the diagonal brace 29 adjacent to said standard, said braces extending downwardly substantially at right angles to the braces 6. The clips 28 are surmounted by caps 30, that in conjunction with said clips form bearings for the shaft 31, upon which is mounted near each of its ends a sprocket-wheel 32.

A bracket is bolted to the lower ends of each of the braces 29, and these brackets are likewise provided with caps 34, which in conjunction with said brackets form bearings for the shaft 35, upon which to the inside of the bracket and adjacent thereto the sprocketwheels 36 are fixed. One end of the shaft 35 is extended through its bearing and carries a sprocket-wheel 37. To the hub of the wheel 1, adjacent to the wheel 37, a sprocket-wheel 88 is fixed, and this sprocket -wheel 38 is adapted to drive the wheel 37 and the shaft 35 and wheels 36 by the chain 39, which connects the wheels 37 38. The wheels 36 and the wheels 32 are likewise connected by a sprocket-chain 40, that carries a series of buckets 41. its lowest point,which brings the buckets close to the surface being swept directly in front of the brush,so that the dirt, (X30. will be swept into said buckets. This horizontal position is obtained by guiding the chain around a roller 43, adj ustably secured to the inner face of each of the lower braces 6. As the buckets pass upwardly after receiving the sweepings the chains 4-0 rest and are guided upon the upper edges of the braces 22). The chains pass downwardly below the braces 29 and over the guide-rollers 30, journaled in the brackets 30 bolted to the said braces, and to adjust the tension thereof plates 44 extend in substantially the direction traveled by the chain and are adapted to be pressed thereagainst, these plates being secured to brackets which are adjustably secured to the hori zontal tie-rods 4E0, bolted to the upper braces 6, the braces 29, and the standards 27.

I A hood 44: extends across the top of the machine above the wheels 32, and this hood has its sides bolted to the sides of the braces 29 and the standards 27. The front of this hood This chain runs horizontally at and a portion of the sides are extended down below the plane of the Wheel 32 and are provided with outwardly-extendin g pins or other suitable fasteners, by which the mouth of a bag 46 may be attached thereto. This bag has a narrow mouth that closely fits over the extended part of the hood and a widened fiat bottom which rests upon the platform, said bag being adapted to receive the sweepings dumped thereinto as the buckets round the wheels 32, and the platform wholly sustains the weight of this bag and its contents, thus relieving the hood from the strain.

The front of the machine is supported by the wheels 47, which are journaled in the upturned ends of the cross-bar 48, extending beneath the platform and suitably pivotally connected thereto,as by a fifth-wheel or otherwise. A rod may extend from this bar back in proximity to the operator, so that he may guide the machine during its progress.

Rods 49 extend from the top of the hood down to the casting 5 parallel to the braces 29, and these rods are adapted to support a suitable apron that may be stretched across the machine above the buckets. A similar apron may be stretched across the machine and secured at its side edges to the under edges of the braces 29.

To the gutter side of the platform, near the front thereof, a gutter-sweeping brush 50 is pivoted, which is provided with a rounded edge. This brush is undertension of aspring 51, which tends to hold it against the stoppin 52, so that it normally extends obliquely from the machine, but it may be pressed inwardly against the tension of said spring should the rounded edge strike the curbing.
